Abstract
A spin wave control device includes a first magnetic layer, a second magnetic layer arranged above the first magnetic layer, and a capping layer overlapping a portion of the second magnetic layer. The first magnetic layer has a magnetization pointing in a first direction and the second magnetic layer has a magnetization pointing in a second direction that is approximately opposite to the first direction. The capping layer has a magnetization pointing approximately in the first direction or approximately in the second direction.

A spin wave control device comprising:
- a first magnetic layer having a magnetization pointing in a first direction;
- a second magnetic layer arranged above the first magnetic layer and having a magnetization pointing in a second direction that is approximately opposite to the first direction;
- and
- a capping layer overlapping a portion of the second magnetic layer or a portion of the first magnetic layer, the capping layer having a magnetization pointing approximately in the first direction or approximately in the second direction.
A method for controlling a polarized spin wave comprising:
- injecting the polarized spin wave into a synthetic antiferromagnet (SyAF);
- and
- controlling a magnetization direction of a capping layer overlapping a portion of the SyAF to rotate a polarization of the polarized spin wave.
A computing device comprising:
- a logic track including two logic-track magnetic domains separated by a logic-track domain wall;
- an input track arranged crossing the logic track at a first position of the logic track, the input track including at least one input-track magnetic domain, and each of the at least one input-track magnetic domain including at least one input-track storage unit configured to store binary 0 or 1;
- and
- an output track arranged crossing the logic track at a second position of the logic track near the logic-track domain wall, the output track including at least one output-track magnetic domain, and each of the at least one output-track magnetic domain including at least one output-track storage unit configured to store binary 0 or 1.
